Answers
Answer:
45 × 4 = (9 × 5) × (2 × 2) = (9 × 2) × (5 × 2) = 18 × 10 = ?
Step-by-step explanation:
Which equation shows one way to find the value of 45 × 4?
45 × 4
Splitting each number into factors of each other
45 = 9 × 5
4 = 2 × 2
45 × 4 = (9 × 5) × (2 × 2)
45 × 4 = (9 × 2) × (5 × 2)
45 × 4 = 18 × 10

Pipe A can fill a tank in 5 hours. Pipe B can fill it in 2 hours less time than it takes pipe C, a draining pipe, to empty the tank. With all 3 pipes open, it takes 3 hours to fill the tank. How long will it take pipe C to empty it?
Answers
Answer: Time taken by pipe C to empty the tank = 5 hours.
Step-by-step explanation:
Pipe A can fill a tank in 5 hours.
Let time taken by Pipe C = x ( hours)
Time taken by Pipe B = x-2 ( hours)
Now, with all 3 pipes open, it takes 3 hours to fill the tank, it can be represented as
[tex]\dfrac15+\dfrac1{x-2}-\dfrac1x=\dfrac 13\\\\\Rightarrow\ \dfrac{x-(x-2)}{x(x-2)}=\dfrac13-\dfrac15\\\\\Rightarrow\ \dfrac{x-x+2}{x^2-2x}=\dfrac{5-3}{15}\\\\\Rightarrow \dfrac{2}{x^2-2x}=\dfrac2{15}\\\\\Rightarrow\ x^2-2x=15\\\\\Rightarrow\ x^2-2x-15=0\\\\\Rightarrrow\ x^2-5x+3x-15=0\\\\\Rightarrow\ x(x-5)+3(x-5)=0\\\\\Rightarrow\ (x-5)(x+3)=0\\\\\Rightarrow\ x=5, -3[/tex]
Time cannot be negative,
So, x=5
Thus, Time taken by pipe C to empty the tank = 5 hours.

Answers
Step-by-step explanation:
2x² + 8x - 1 = 0
2(x + 2)² - 9 = 0
2(x + 2)² = 9

x = √4.5 - 2 or x = -√4.5 - 2
x = 0.12 or x = -4.12.
slope and y intercept of 5x + 8y = 8
Answers
Answer:
Slope: -5/8
y intercept: (0,1)
Step-by-step explanation:
The slope of the line will be {m} = -5/8 and the y - intercept will be 1.
What is direct variation?Direct variation of a quantity {y} with respect quantity {x} means that the value of {y} increases as the the value of {x} increases. Mathematically -
y = Kx
K = y/x
where -
{K} is scale factor. It also tells by how many times is {y} greater than {x}.
Given is the equation of a straight line as -
5x + 8y = 8
We can rewrite the equation as -
5x + 8y = 8
8y = - 5x + 8
y = -(5/8)x + 1
So the slope will be -
m = -(5/8)
c = 1
Therefore, the slope of the line will be {m} = -5/8 and the y - intercept will be 1.

Use the figures to complete the statements proving the converse of the Pythagorean theorem.
Drag and drop a phrase, value, or equation into the box to correctly complete the proof.
To prove the converse of the Pythagorean theorem, we must show that if △ABC has sides of a, b, and c such that a² + b² = c² , then △ABC is a right triangle.
Define △DEF so that it is a right triangle with sides a, b, and hypotenuse x. By the Pythagorean theorem, a² + b² = x² .
Since a² + b² = c² and a² + b² = x², it must be true that c² = x². Since sides of triangles are positive, then we can conclude that Response area. Thus, the two triangles have congruent sides and are congruent.
Finally, if △ABC is congruent to a right triangle, then it must also be a right triangle.
Two right triangles with points labeled in capital letters and sides labeled in lower case letters.

Jade has 100 to spend on shoes and socks. She buys a pair of shoes for 75 and wants to wants to spend the rest of the money on socks. Each of socks cost $3.50. let n represent the number of the pair of socks that jade can buy. Which inequality represents her situation?
Answers
Answer:
75 + 3.5n ≤ 100
Step-by-step explanation:
Given that:
Total amount = $100
Cost of shoe = $75
Cost per socks = $3.50
n = number of socks pairs
Cost of shoe + (cost per pair of socks * number of socks) ≤ total amount
75 + (3.50 * n) ≤ 100
75 + 3.5n ≤ 100
Give Nitroprusside 5 mcg/kg/minute via continuous infusion for a patient weighing 205 lbs. Nitroprusside is available in a solution of 200 mg in 250 mL D5W. What rate on the infusion pump will deliver the correct dose?
Answers
Answer:
35 ml/hr
Step-by-step explanation:
Convert lbs to kg
205 ÷ 2.2 = 93.18 = 93.2 kg
Calculate the minute rate
93.2 kg x 5 mcg/kg/min = 466 mcg/min
Calculate hourly rate
466 mcg/min x 60 mins/hr = 27,960 mcg/hr
Drug is expressed in mg, so convert mcg to mg
27,960 mcg = 27.96 mg
"The difference between four-fifths of
a number and 11 is -46."
Answers
Answer:
The number is -43.75.
Step-by-step explanation:
4x/5 - 11 = -46
4x/5 = -35
x = -43.75
Answer:
-43.75
Step-by-step explanation:
This is the answer because:
1) We know that 4/5 of a number has to equal -35 since -46 + 11 = -35.
2) 4/5x = -35 (solve for x): -35 ÷ 4/5 = -43.75
3) 4/5 x -43.75 = -35, I got this by solving for x (look at step 2)
Therefore, the answer is -43.75

1.5:4=9:(2y+5)
Solve for y
Answers
Answer:
y = 9.5
Step-by-step explanation:
Express the ratios in fractional form, that is
[tex]\frac{1.5}{4}[/tex] = [tex]\frac{9}{2y+5}[/tex] ( cross- multiply )
1.5(2y + 5) = 36 ( divide both sides by 1.5 )
2y + 5 = 24 ( subtract 5 from both sides )
2y = 19 ( divide both sides by 2 )
y = [tex]\frac{19}{2}[/tex] = 9.5
